We want to build tiny gnat-sized robots, a millimeter or two in diameter. They will be cheap, disposable, totally sefcontained autonomous agents able to do useful things in the world. This paper consists of two parts. The first describes why we want to build them. The second is a technical outline of how to go about it. Gnat robots are going to change the world.

In this article I challenge two arguments central to Hugh Baxter's critical interpretation of Habermas in his recent book, Habermas: The Discourse Theory of Law and Democracy (2011). Both arguments focus on whether Habermas’ system -lifeworld model of society can successfully make space for democratic politics. Baxter highlights problems with both Habermas’ The Theory of Communicative Action [hereafter cited as TCA] and Habermas’ attempts to fix those problems in Between Facts and Norms [hereafter cited as BFN]. Thus, engaging Baxter on (...) these issues provides an opportunity to think about how to read two of Habermas’ most significant texts in relation to each other. Baxter stresses discontinuities but I draw attention to important continuities. The first discontinuity highlighted by Baxter is between TCA's functionalism and BFN's normative approach. By contrast, in section I my article stresses elements of TCA that have been under-appreciated in general and by Baxter in particular, challenging us to rethink aspects of the standard reading of functionalist versus normative moments in the trajectory of Habermas’ thought. More specifically, in the second discontinuity Baxter identifies in BFN a significant shift in Habermas’ understanding of the nature of a ‘system’. I challenge this interpretation in section II and provide what I think is a superior reconstruction of the model presented in BFN. (shrink)

Discrete choice experiments—selecting the best and/or worst from a set of options—are increasingly used to provide more efficient and valid measurement of attitudes or preferences than conventional methods such as Likert scales. Discrete choice data have traditionally been analyzed with random utility models that have good measurement properties but provide limited insight into cognitive processes. We extend a well-established cognitive model, which has successfully explained both choices and response times for simple decision tasks, to complex, multi-attribute discrete choice data. The (...) fits, and parameters, of the extended model for two sets of choice data (involving patient preferences for dermatology appointments, and consumer attitudes toward mobile phones) agree with those of standard choice models. The extended model also accounts for choice and response time data in a perceptual judgment task designed in a manner analogous to best–worst discrete choice experiments. We conclude that several research fields might benefit from discrete choice experiments, and that the particular accumulator-based models of decision making used in response time research can also provide process-level instantiations for random utility models.

This paper explores the conduct of performance appraisals of nurses in a New Zealand hospital, and how fairness is perceived in such appraisals. In the health sector, performance appraisals of medical staff play a key role in implementing clinical governance, which, in turn, is critical to containing health care costs and ensuring quality patient care. Effective appraisals depend on employees perceiving their own appraisals to be fair both in terms of procedure and interaction with their respective appraiser. We examine qualitative (...) data from interviews and focus groups, involving 22 nurses in a single department, to determine whether perceived injustices impact on the effective implementation of the appraisal system. Our results suggest that particular issues had been causing some sense of injustice, and most of these were procedural. Potential solutions focus on greater formalisation of the performance appraisal process, and more training for appraisers and appraisees. (shrink)

In this book, Flynn stresses the vital role of intercultural dialogue in developing a non-ethnocentric conception of human rights. He argues that Jürgen Habermas’s discourse theory provides both the best framework for such dialogue and a much-needed middle path between philosophical approaches that derive human rights from a single foundational source and those that support multiple foundations for human rights . By analyzing the historical and political context for debates over the compatibility of human rights with Christianity, Islam, and "Asian (...) Values," Flynn develops a philosophical approach that is continuous with and a critical reflection on the intercultural dialogue on human rights. He reframes the dialogue by situating it in relation to the globalization of modern institutions and by arguing that such dialogue must address issues like the legacy of colonialism and global inequality while also being attuned to actual political struggles for human rights.

Abstract This paper puts Searle?s social ontology together with an understanding of the human person as inclined openly toward the truth. Institutions and their deontology are constituted by collective Declarative beliefs, guaranteeing mind-world adequation. As this paper argues, often they are constituted also by collective Assertive beliefs that justify (rather than validate intrainstitutionally) institutional facts. A special type of Status Function-creating ?Assertive Declarative? belief is introduced, described, and used to shore up Searle?s account against two objections: that, as based on (...) collective acceptance, Searlean social ontology cannot make sense of dissenters, and that it, as its deontology is all game-like, implies a legal positivism and thus cannot make proper sense of the moral import of sociopolitical institutions. This change is necessary to deepen social ontology?s understanding of human societies and to accurately describe many social, religious, and political institutions as constituted from the perspectives of participants and dissidents.

What types of unity and disunity belong to a group of people sharing a culture? Husserl illuminates these communities by helping us trace their origin to two types of interpersonal act—cooperation and influence—though cultural communities are distinguished from both cooperative groups and mere communities of related influences. This analysis has consequences for contemporary concerns about multi- or mono-culturalism and the relationship between culture and politics. It also leads us to critique Husserl’s desire for a new humanity, one that is rational, (...) cooperatively united, and animated by a universal philosophical culture. Reflecting on culture, a spiritually shaped and shared domain of the world, draws us to reflect also on ourselves as social and rational animals, and to ask, what should we reasonably hope for—and aim for—in a human culture that expresses and supports our shared lives of reason? Aristotle is used for occasional comparisons and contrasts. (shrink)

The present study examined whether strategy moderated the relationship between visuospatial perspective-taking and empathy. Participants undertook both a perspective-taking task requiring speeded spatial judgements made from the perspective of an observed figure and the Empathy Quotient questionnaire, a measure of trait empathy. Perspective-taking performance was found to be related to empathy in that more empathic individuals showed facilitated performance particularly for figures sharing their own spatial orientation. This relationship was restricted to participants that reported perspective-taking by mentally transforming their spatial (...) orientation to align with that of the figure; it was absent in those adopting an alternative strategy of transposing left and right whenever confronted with a front-view figure. Our finding that strategy moderates the relationship between empathy and visuospatial perspective-taking enables a reconciliation of the apparently inconclusive findings of previous studies and provides evidence for functionally dissociable empathic and non-empathic routes to visuospatial perspective-taking.

Life expectancy and health differ greatly between emerging and developed countries and within countries. Global dependence on fossil fuels contributes to health inequalities through air pollution, the geopolitics of scarce resources and probable climate change arising from global warming. Substituting for fossil fuels (C), hydrogen (H2), as vector and store of energy produced from low-carbon and/or renewable sources could reduce health inequalities by improving the environment. It is unlikely that the global market would initiate such a change. Nation-states would not (...) act alone and would need to cooperate in leading it. Global recession might be the incentive that is needed to restructure a C-economy into an H2-economy. Yet, the transition would carry high costs, which would have to be borne by the developed countries in order to achieve a new treaty that included emerging countries. H2 for C is thus not only a technical fix, but also a global-ethical choice. (shrink)

This paper formulates a vision for leadership based on integrity in business, banking, government and politics. It proposes a tripartite response to the current grave difficulties affecting international finance and markets: a renewal of values and virtues, acceptance of the centrality of the human person, and appropriate recourse to key principles of Catholic social teaching, as articulated in Pope Benedict XVI’s encyclical, Caritas in Veritate. By considering Ireland’s “Celtic Tiger” period, particularly the actions of the Anglo Irish Bank, we show (...) how failures in leadership and integrity at all levels of Irish society, including business, politics, government, public sector and church, have eroded trust and damaged the reputation of key institutions. The paper presents plain suggestions for civic leaders on how putting people first can help restore trust, reputation, integrity and professionalism at local and global levels. (shrink)

This article briefly reviews concerns related to the “cultural colonialism” of applying Western biomedical models of research ethics to non-Western groups. The feasibility of alternate ethical models is discussed and found wanting. In practical terms, many academic researchers in the United States are funded by federal agencies and are required to adhere to Title 45, Part 46 of the Code of Federal Regulations , legislation that is clearly grounded in the Western biomedical research tradition. Consequently, the question is not whether (...) this system of ethics should be applied but rather how it can be applied most sensitively, appropriately, and wisely. The remainder of this article discusses of how the authors have attempted to do so in each stage of their own research with Hispanic immigrants to the United States. (shrink)

The crucial distinction for ethics is between the good and the apparent good, between being and seeming. Tradition is useful for developing our ability to make this distinction and to live ethically or in self-responsibility, but it is also threatening to this ability. The phenomenology of Husserl and of others in the Husserlian tradition, especially Robert Sokolowski, are helpful in spelling out how tradition works; how the difference between the apparent good and the good is bridged in the experience of (...) moral truth but also a permanent, challenging feature of human life; what ethics requires regarding self-responsibility or authenticity; and what the proper voice of tradition is in the ethical or moral life.

“Dialectical” stands in parentheses because I wish to discuss both authors in terms of a critique of reason as such in addition to specifying the issue in terms of their respective assessments of the dialectic. But I shall first consider how each employs the term “critique.” So my remarks will focus on Critique, Reason and Dialectic in that order. Of course, each topic understandably bleeds into the others. In view of the occasion, I shall conclude with a brief sketch of (...) four milestones along Sartre's way from Being and Nothingness to the Critique. (shrink)
